@Gargron the question assumes that "percentages" already have a meaning before you try to get "100%". Percentages of what? If you want to show the relative strengths of each option, then the number of users who voted are irrelevant, and it's a matter of showing 100 * optionVoteCount / totalVoteCount for each option. And then that result tells you how to rank the options, but nothing about the _popularity_ of each option. For that, you'd need to weigh votes based on how many things a user voted.
